简要总结
Gene transfer by electroporation (gene electrotransfer) uses short electric pulses to transiently permeabilise the cell membrane enabling passage of plasmid DNA into the cell cytosol. It is an efficient non-viral method for gene delivery to various tissues. In this phase I dose-escalating study, patients will be treated with intramuscular gene electrotransfer of plasmid AMEP. Plasmid AMEP encodes protein AMEP which bind to α5β1 og αvβ3 integrins. Primary end point of the trial is safety and secondary end points are efficacy, pharmacokinetics and evaluation of potential discomfort associated with the treatment procedure using VAS (Visual Analogue Scale).
详细描述
Cohorts of 3 patients will be treated with increasing doses of plasmid AMEP. Up to 12 patients will be treated.
Treatment procedure: Local anesthetic is applied to m. quadriceps femoris (thigh muscle) and the skin. An incision of the skin is performed followed by dissection until the muscle is exposed. The surgical procedure is performed by plastic surgeons.
Plasmid AMEP is injected intramuscularly and immediately followed by application of electric pulses via a needle electrode inserted into the muscle. A combination of one high voltage pulse (700V/cm, 100 µs) followed by one low voltage pulse (80 V/cm, 400 ms) will be applied. The wound is sutured and a dressing is applied. Treatment procedure is estimated to 30 minutes.
All patients are hospitalized for 24 hours after treatment for the purpose of evaluation of vital signs, physical examination, AE and SAE recording and pharmacokinetics sampling (blood and urine).
Blood biochemistry including LDH and CK is taken 24 hours post treatment. ECG will be taken before and after treatment. Patients score discomfort or pain from treated area using VAS.

结局指标
主要结局
Safety of the trial treatment
时间窗: From treatment to last follow up, planned 8 weeks.
Safety is evaluated by registration of adverse events (Adverse Events and Serious Adverse Events) using the CTCAE criteria version 4.0. Patients are seen in the out patient clinic once a week during the first month after treatment (at day 8, day 15, day 22, day 29) and 8 weeks after treatment. If no progression of the disease at 8 weeks, patients are seen at 12 weeks and then every three months until disease progression or death.
次要结局
- Efficacy of the trial treatment(PET/CT scan 4 weeks, 8 weeks and 12 weeks after trial treatment.)
- Pharmacokinetics(Pre-dose, 2, 6 and 24 hours after dose, day 8, 15, 22, 29 and 8 weeks after treatment.)
- Discomfort associated with the treatment procedure(Scoring 'immediately after treatment', '30 min after treatment' '6 hours after treatment' and 'pain in the past 24 hours', and day 8.)
- Safety(Day after treatment and 14 days after treatment)
